First and foremost, sorry for the loss. Dealing with a Model Builders/Collectors collection is a very time consuming affair. I have helped two families dispose of such collections and it is not easy. Lots of work and time goes into getting rid of what took so long to gather. It is a labor of love. I did it because they where dear friends of mine, otherwise I would have wished them luck and moved on. Do what you feel is right, if you wish to pass it on, then do so with no regret, and if you choose to deal with it, be very patient. Just my thoughts
